There's definitely a similarity in style which is cool but I don't think it's from the Prometheus.

I'm finding it difficult to find proof that it is from the Prometheus, other than the fact that it says P-01 on it. I just find it difficult to imagine how a chunk of the Prometheus would manage to escape lv223's gravity when the ship exploded so close to the surface. But then again, this is the sequel to Prometheus.I think it more likely that it's simply part of the ship that this new crew of explorers used to get to "uncharted paradise", but is in fact a planet inhabited by loads of davids.

Also, it just occurred to me, does anyone else think the deacon could've stowed away on the engineer ship shaw took? I mean, it never really shows for certain whether or not shaw had taken off before the deacon hatched. Only that it showed shaw taking off in a separate scene just before the scene with the deacon. So, there is actually a bit of an ambiguity here. PLUS, Ridley said there was gonna be every type of xeno in Alien: Covenant and what are the odds of there being 2 deacons created? Not high I imagine.

What I'm saying is that with the tide, the ship could be in the water at some point during the day and on land on another time of day. Anybody know if this sort of thing happens in this area? It seems like it might. A satellite image from Google maps can clarify that for us if we get them from different moments. It would also be interesting to point out the exact location of the ship on the google map, but so far I can't seem to pinpoint the spot. Anyone?

You'd be surprised how big an explosion they can make these days without actually damaging anything around it. Some of those recent shots look a little singed, so it's not beyond the realms of possibility it survived intact.
